Abstract
When it comes to knowledge bases most people's first thought are structured sources
such as the Freebase/Wikidata and their relationship to similarly structured web
sources such as Wikipedia. A lot of additional and interesting "knowledge" though
is captured in unstructured databases constructed in a less supervised manner using
open information extraction techniques. In this talk we'll discuss some of the
differences between open/closed schema knowledge bases including the ideas of
objective vs subjective content as well as freshness and trust. We'll give an
overview on approaches to aligning such data sources in a way that their relative
strengths can be combined and finish with applications of such alignments;
particularly around open question and answer systems.
